This invention relates to a paring or scraping tool, and particularly toa gauge tool adapted for use by either right orleft-handed operators.

It is an object of this invention to provide a very simple, efiicientand inexpensive paring or scraping tool having spaced blades withcutting edges facing in substantially opposite directions and havinggauge portions spaced from said blades transversely thereof andextending longitudinally of said blades, said portions preferably havingcurved convex surfaces at the sides adjacent said blades.

It is also an object of .the invention to provide such a tool as setforth in the preceding paragraph, the same being formed of one integralpiece of material and having a substantially cylindrical eye-cutting andcoring member at one end adjacent said blades, the same being disposedcentrally of said blades and having its axis extending at substantiallyright angles to the edges of said blades.

It is still further an object of the invention to provide a gauge paringor scraping tool adapted for use by right and left-handed operators, thesame being formed of one piece of sheet metal and having spaced bladeswith cutting edges facing in substantially opposite directions, gaugeportions extending longitudinally of said blades and spaced from said.blades transversely thereof and extending away from said blades incurved formation, said piece having a handle portion extending at oneend spaced from said blades and disposed centrally thereof.

It is more specifically an object of the invention to provide a paring,scraping and coring tool formed of one integral piece of material, saidpiece having spaced blades punched therefrom, having cutting edgesdiverging slightly toward one end of said piece, said piece being ofangular inverted trough shape between said blades, gauge portionsextending longitudinally of said blades respectively and spacedtherefrom transversely of said blades, said gauge portions extendingaway from said blades in curved form with their convex sides adjacentsaid blades, said piece having a handle formed therein extendinglongitudinally at one end of said blades and centrally thereof, saidhandle having upper convex sides and end, said piece having also asubstantially cylindrical eye-cutting and coring member formed at theend thereof opposite said handle and disposed centrally of said blades,the same having its. axis extending substantially at right angles tosaid edges. I

These and other objects and advantages ofythe invention will be fullyset forth in the following description made in connection with theaccompanying drawings in which like reference characters refer to thesame parts throughout the several views and in which:

Fig. 1 is a top plan view of said tool.

Fig. 2 is a view in side elevation of said tool.

Fig. 3 is a partial view in side elevation showing a modification.

Fig. 4 is a partial vertical section taken on line 4- 4 of Fig. 1.

Fig. 5 is a vertical section taken on line 5-5 of Fig. 1.

Fi 6 is a vertical section taken on line 6-6 of Fig. 1, and

Fig. '7 is a partial plan view of the blank used in forming said tool.

Referring to the drawings, a tool is shown having spaced blades l0.Blades I0 are provided with sharpened cutting edges Illa facing insubstantially opposite directions. While blades l0 could be variouslyformed, in the embodiment of the invention illustrated, they are formedof one piece of material, and as shown in Fig. 5 this piece of materialis of inverted angular trough shape between said blades. The bottom ofsaid trough is thus disposed upwardly. A gauge portion H is provided foreach blade, and as shown in Fig. 5 each portion II is spaced from itsblade l0 transversely of said blade, the same extending longitudinallyof said blade substantially parallel thereto and extending away fromsaid blade in curved form. The convex side of each gauge portion H is atthe side thereof adjacent its blade. In the embodiment of the inventionshown in Figs. 1 and 2, the tool is made froman integral piece of sheetmetal. It will be noted that the blades I 0 diverge slightly toward oneend of the tool and a handle portion I2 extends from said endlongitudinally of and centrally of blades 10. Handle I2 is shown asprovided with spaced holes 13 and I4. Handle l2 has its side edgesdiverging towards its outer end and said handle is of inverted troughshape, the sides and end thereof being curved with their convex sidesupwardly. The integral piece of metal from which the tool is made hasformed at one end thereof opposite the handle and a substantiallycylindrical eye-cutting and coring member 15. Member l5 has its axisextending at substantially right angles to the edges of blades l0, andthe circular edges at each side of member l5 are sharpened, as shown inFigs. 1 and 6. The width of member 15 increases from its inner to itsouter side. A portion of the blank from which 2,488,517 3 4 the tool ismade is shown in Fig. 'l and is in its in the steps and sequence ofsteps of the method form before the member l5 has been formed withoutdeparting from the scope of applicants thereon.
